TIPS:

Add context menu for easy check from challange.txt or client_id_blob

INSTRUCTIONS:

• Just double click the add_context_menu.bat to automatically add context menu into your registry
• You can also change the context title ("Check Client Id Blob") inside the bat file
• Now you can do like the ss below or you can just drag and drop the file in the bat file

From client_id_blob

From challange.txt

CHANGELOGS

[1.0.7] | 2022-01-28

• Automatically run "add_context_menu.bat" as admin
• Don't write challenge.txt automatically
• Print client id blob basic info if --quite mode enabled
• Prompt to load challenge from "challenge.txt" if input is empty
• Colored is now optional (see config.py)
  • NOTE: For windows 7, if you want to print colored text, you can use ansicon.
  • INSTRUCTIONS:
    • Extract the zip file
    • Take the folder (x86 if you are using 32bit / x64 if 64bit) and place somewhere and then add the binary to your Environment Variables
    • Simply run for the first time in your cmd: ansicon -i
    • Now it should be injected to your cmd and colored text should show normally.

---

[1.0.6] | 2022-01-23

• Saving file is now optional (add --save arg to save the file)
• Added os_version info

---

[1.0.5] | 2022-01-08

• Removed context_menu.reg and replaced with batch file instead to automatically assign the current check.bat full path
• Added current full path in check.bat instead of adding manually
• Renamed proto to wv_proto to avoid conflict from proto import
• colored output for device info and logger
• You can edit the output file name format (see in config.py)
• And some little changes
